WARNING, MINOR SPOILERS: Mass Effect 2's plot focuses around the abduction of many humans from colonies out in the Terminus Systems. After being killed in action, Shepard is resurrected by the human extremist organization, Cerberus. They inform Shepard that he has been dead for 2 years and the Alliance hasn't done any investigation into Shepard's death or the abductions. Shepard is instructed to recruit a crew of deadly operatives and take down a mysterious alien race called the Collectors. After acquiring the necessary technology to pass into uncharted space, Shepard locates the Collector home ship and cleanses it of all Collector life forms.
